A New Ultra-dense Group of Obscured Emission-Line Galaxies
نویسنده
چکیده
We present the discovery of an isolated compact group of galaxies that is extremely dense (median projected galaxy separation: 6.9 kpc), has a very low velocity dispersion (σ2D = 67 km s −1), and where all observed members show emission lines and are morphologically disturbed. These properties, together with the lack of spirals and the presence of a prominent tidal tail make this group one of the most evolved compact groups. Subject headings: galaxies: compact — galaxies: interactions — galaxies: starburst — galaxies: evolution

EMISSION-LINE OBJECTS FROM A PRELIMINARY UKST OBJECTIVE PRISM SURVEY
A visual search has been made of four fields using United Kingdom 1.2m Schmidt Objective Prism plates with a reciprocal dispersion of 1 180 A/mm at HP. Such plate material is ideally suited to searches for emission-line galaxies. We present a catalogue of 53 emission-line objects, which comprises 45 galaxies, where individual HI1 regions are resolved in 16 bright galaxies; 8 are emission li...
متن کاملAGN Zoo and Classications of Active Galaxies
We review the variety of Active Galactic Nuclei (AGN) classes (so-calledAGN zoo") and classification schemes of galaxies by activity types based on their optical emission-line spectrum, as well as other parameters and other than optical wave-length ranges. A historical overview of discoveries of various types of active galaxies is given, including Seyfert galaxies, radio galaxies, QSOs, BL Lace...
متن کاملWhere Is the [o Iii]λ4363 Emitting Region in Active Galactic Nuclei?
The emission-line flux ratio of [O iii]λ4363/[O iii]λ5007 (ROIII) is a useful diagnostic for the ionization mechanism and physical properties of emission-line regions in active galactic nuclei (AGNs). However, it is known that simple photoionization models underpredict the [O iii]λ4363 intensity, being inconsistent with observations. In this paper, we report on several pieces of evidence that a...
متن کاملDenis Detections of Highly Obscured Galaxies in the Area around Pks 1343 – 601
We present results of a search for galaxies around the highly obscured giant radio galaxy PKS1343– 601 using the near-infrared DENIS survey. We compare our findings with surveys in the B-band, at the 21 cm line emission, and with 2MASS. Recession velocities of galaxies in this area suggest a low-velocity-dispersion group or cluster of galaxies including an X-ray confirmed Seyfert 2. The colours...

We describe the far-infrared (far-IR; rest-frame 8–1000-μm) properties of a sample of 443 Hαselected star-forming galaxies in the Cosmic Evolution Survey (COSMOS) and Ultra Deep Survey (UDS) fields detected by the High-redshift Emission Line Survey (HiZELS) imaging survey. Sources are identified using narrow-band filters in combination with broad-band photometry to uniformly select Hα (and [O I...
